Water Resources Division, U.S. Geological Survey, Mary C. Rabbitt
1975, Report
Established by an Act of Congress in 1879 and charged with responsibility for "classification of the public lands, and examination of the geological structure, mineral resources, and products of the national domain," the U. S. Department of the Interior's Geological Survey has been the Nation's principal source of information about...
Quantitative determination of dawsonite in Green River Shale by powder-sample X-ray diffraction; effect of grinding
E-an Zen, Jane M. Hammarstrom
1975, Journal of Research of the U.S. Geological Survey (3) 21-30
In an effort to evaluate the method of quantitative analysis by X-ray diffraction as a means of determining dawsonite abundances in Green River" oil shale, we performed a series of grinding experiments. Weighed mixtures of dawsonite + quartz and dawsonite + quartz + shale were ground for preset lengths of...
Water resources inventory of Connecticut Part 5: lower Housatonic River basin
William E. Wilson, Edward L. Burke, Chester E. Thomas Jr.
1974, Connecticut Water Resources Bulletin 19
The 557 square miles of the lower Housatonic River basin in western Connecticut include the basins of two major tributaries, the Pomperaug and Naugatuck Rivers. Nearly all water is derived from precipitation, which averaged 47 inches per year during 1931-60, In this period an additional 570 billion gallons of water...
Bimodal tholeiitic-dacitic magmatism and the Early Precambrian crust
F. Barker, Z. E. Peterman
1974, Precambrian Research (1) 1-12
Interlayered plagioclase-quartz gneisses and amphibolites from 2.7 to more than 3.6 b.y. old form much of the basement underlying Precambrian greenstone belts of the world; they are especially well-developed and preserved in the Transvaal and Rhodesian cratons. We postulate that these basement rocks are largely a metamorphosed, volcanic, bimodal suite...

Flashing flow in hot water geothermal wells
Manuel Nathenson
1974, Journal of Research of the U.S. Geological Survey (2) 743-751
The production characteristics of hot-water geothermal wells which flash to steam-water mixtures in the cased part of the hole were-analyzed. The flashing flow is assumed to be isenthalpic and, for purposes of calculating pressure drop, a finely dispersed mixture of equal average velocity. Water flow in the aquifer is treated...

Geochemical survey of the western coal regions; first annual progress report, July 1974
Jon J. Connor, Ronald R. Tidball, James A. Erdman, Richard J. Ebens, John R. Keith, Barbara M. Anderson
1974, Open-File Report 74-250
National energy needs have precipitated an increased interest in the development of a large coal-based electric power industry in the western United States. This anticipated development has, in turn, spawned a great deal of interest in the environmental impact consequent upon the mining and utilization of these coal supplies. Numerous...
A preliminary report on a zone containing thick lignite beds, Denver Basin, Colorado
Paul E. Soister
1974, Open-File Report 74-27
A zone of lignite beds of Paleocene age in the Denver Formation (Upper Cretaceous and Paleocene) lies about 800-1,500 feet above the well-known and extensively mined coal beds of the Laramie Formation (Upper Cretaceous). The zone is a few hundred to as much as 500 feet thick. Where lignite beds...
Red Sea geochemistry
Frank T. Manheim
1974, Initial reports of the Deep Sea Drilling Project (23) 975-998
The Red Sea drillings reveal a number of new facets of the hot-brine-metalliferous system and other geochemical aspects of the sea, its sediments, and its past history as follows: 1) Dark shales rich in organic material, and containing enhanced Mo and V concentrations, are characteristic of Plio-Pleistocene strata in the...
Origin of Franciscan melanges in Northern California
M. Clark Blake Jr., D. L. Jones
1974, SEPM Special Publication 19
In northern California, chaotic Franciscan melange occurs beneath the overlying ophiolite and Great Valley Sequence. Identical melanges occur to the west, separating well-bedded, coherent Franciscan units that differ markedly in age. Detailed studies in several places indicate that these melanges mark the boundaries of imbricate thrust sheets, and they appear...
Equilibria of cinnabar, stibnite, and saturated solutions in the system HgS-Sb2S3-Na2S-H2O from 150° to 250°C at 100 bars, with implications concerning ore genesis
R. E. Learned, G. Tunell, F. W. Dickson
1974, Journal of Research of the U.S. Geological Survey (2) 457-466
The common occurrence of cinnabar and stibnite in well-defined districts in the same epithermal environments suggests that similar physiochemical processes are responsible for the genesis of the two minerals; however, cinnabar and stibnite tend to be segregated within these districts and also within individual deposits that contain both minerals. Where...
Preliminary study of rock alteration in the Catheart Mountain molybdenum-copper deposit, Maine
Robert G. Schmidt
1974, Journal of Research of the U.S. Geological Survey (2) 189-194
Studies of drill cores from the Catheart Mountain molybdenum-copper deposit indicate that the deposit is of the porphyry type. Hydrothermal alteration and sulfide mineralization are probably distributed in complex but systematic alteration zones. Most or all mineralization at Catheart Mountain is in a medium-fine-grained quartz monzonite enclosed within a larger...
Stable isotope and lead isotope study of the Cortez, Nevada, gold deposit and surrounding area
R. O. Rye, B. R. Doe, J. D. Wells
1974, Journal of Research of the U.S. Geological Survey (2) 13-23
Isotope studies of sulfur, carbon, hydrogen, oxygen, and lead were carried out to clarify the age and origin of the Cortex gold deposit and the surrounding mineralized area. The hydrogen isotope data indicate that meteoric water was the dominant component of the ore-forming fluids at Cortez. The hydrogen isotope data support geologic evidence for a...

Alton F. Robertson
1973, Florida Bureau of Geology Report of Investigations 64
The Lakeland ridge area of this investigation covers about 300 square miles in northwest Polk County in central Florida. The growth of industry, phosphate mining, and citrus production as well as population growth during the last two decades has resulted in an increase in ground-water pumpage from about 11 billion...
Mechanisms of high-temperature, solid-state flow in minerals and ceramics and their bearing on the creep behavior of the mantle
Stephen H. Kirby, C.B. Raleigh
1973, Tectonophysics (19) 165-194
The problem of applying laboratory silicate-flow data to the mantle, where conditions can be vastly different, is approached through a critical review of high-temperature flow mechanisms in ceramics and their relation to empirical flow laws. The intimate association of solid-state diffusion and high-temperature creep in pure metals is found to...
